4. Goodwill

The Company tests its goodwill for impairment annually in the fourth quarter, and whenever events or changes in circumstances indicate that the carrying value may exceed its fair value.

The changes in the carrying amount of goodwill by reporting unit for the six months ended June 30, 2012 were as follows:

			Currency
	December 31,		translation			Other		June 30,
In thousands	2011		adjustments			adjustments		2012
Performance Materials	$	13,399	$	(104	)	$	63	$	13,358
Other Products and Services		4,660		-			-		4,660
Total goodwill	$	18,059	$	(104	)	$	63	$	18,018

Other adjustments relate to contingent consideration owed to the seller of DSM Solutech B.V. (“Solutech”) which was acquired by the Company in December 2008. Consideration equals 4.0% of Solutech’s net revenues (included in the Performance Materials segment), as defined, and increases the amount of goodwill previously recorded, as the acquisition occurred prior to the revised guidance issued by the Financial Accounting Standards Board (ASC 805) for business combinations.
